地铁通信无线系统设备安装的工艺讨论

Discussion on Installation Process of Subway Communication Wireless System

介绍地铁系统中乘客信息系统的原理及功能实现,针对武汉地铁7号线实际施工过程中发现的乘客信息车地无线天线可能发生侵限的问题,采用实地勘察和理论推演,最终确定将天线改装在布放弱电电缆的五层托架上,经实地测量,问题得到解决,为往后地铁施工及设计提供宝贵经验。

This paper intoduces the principle and flmction realization of passenger infomation system in Metro of the problem that the vehicle-ground wireless antenna of passenger information may intrude during the actual construction of Wuhan Metro Line 7,the field investigation and theoretical deduction are used to determine the modification of the antenna on the five layer bracket of the weak electric cable.Through field survey,the problem has been solved,which will provide valuable experience for subway construction and design in the future.
